BMW 5 Series: From today are 520d sedan and Touring Mild Hybrid 48 V



Also BMW "bends" to the electrification "light" of the series, a solution that is mainly due to the ever stricter European regulations regarding CO2 emissions. As with Audi, BMW and many other manufacturers, the gasoline and diesel engines receive the electric "l? Aiutino", a small generator / starter, which is powered by a 48-V electrical system (19459003) to reduce fuel consumption , and Emissions without Impairment Guide to the Differences Between Hybrid Cars .

The BMW Series 5 is the first model in the range to support the Mild Hybrid first in the most popular version, the 520d . Available from November in both Body and Sedan and Touring . This 2-liter twin-turbo diesel is gaining in power (although it has 1

90 hp at maximum power on the technical data sheet [19459003verbleibt)]), but also in efficiency since consumption drops to an average of 0.3 liters of diesel per 100 km .

The merit is the presence of the generator / starter acting as small electric motor for to reduce the load of the thermal engine and to recover at the same time , kinetic energy when braking which would otherwise be reduced. In practice, the system increases the potential of the existing BMW Energy Recovery System by charging a auxiliary battery for to provide the engine with more power at high power requirements. Not only that: The main function of this small electric motor is to support the heat engine and operate it in the ideal regime to curb consumption and emissions.

Thanks to the improved electrical system the operating range of the Auto Start Stop function (Start & Stop) expands: The heat engine stops before stopping at the traffic light and can stop completely in the mode Sailing . Then the reignition takes place more gently. All of these solutions allow the BMW 520d rear-wheel drive sedan to provide a combined consumption (in the WLTP cycle) of 4.1 to 4.3 l / 100 km and CO2 emissions between 108 and 112 g / km. Values ​​that range up to 4.9 l / 100 km and 124-128 g / km, if you opt for the touring body with all-wheel drive .
